Our first instinct was that it was an osprey - it looked huge, and had a white breast and dark wings, which would be consistent with an osprey. But when we looked through the scope it was clear that it was not.
The rusty blush to the neck and white underside from breast to tail were key points we noticed, and while we haven't definitively identified it, we think it may be an immature Swainson's hawk, though these are generally seen somewhat further west. We welcome comments from those more expert than we are. We had four field guides out while looking at the photos and still could not come up with a definitive ID, even though Dave has taken a hawk identification class. Frustrating!
Here's a view of one of the lakes in the area. This was fairly typical of a lot of the area - lots of marshy wetland (currently fairly dry), some pools and lakes, and some open grasslands and woods as well.
A bit later, while wending our way around the ponds (called pools) of the area, we saw this kingfisher fly overhead. We stopped and walked for a bit and it kindly sat long enough that we could get a photo.
Further along we got this great view of a great blue heron somewhat camouflaged in the reeds.
Here it was hunkered down with its neck retracted in a S shape. I haven't seen herons without their necks extended before.
